Worth checking her nights before you file this as nothing, because daytime sleep is sometimes a bird catching up. Most avian sources land around ten to twelve hours of dark and quiet, and a cage in a room where the television runs until eleven does not deliver that even with a cover on.
Same bedtime, same wake time, dark room away from the household. Better nights also take the edge off hormonal behaviour and general crankiness, which with a conure is not a small benefit.
